Even though I was several hours later than I expected to arrive from the airport, my friends helped me to contact the host. However, if you do not speak or read Thai, be sure you note how to contact the host. You will need to have a phone w/ a SIM card that can be used in Thailand. (I bought a SIM card and had friend's help).
During the daylight hours and into the early evening, there was always someone who was in the (air-conditioned) office. This is more like an apartment building and not a home.
Having the convenience of a 7-11 across the street was handy for snacks, meals and drink!
